abac-mongodb v0.0.0

abac-mongodb

An ABAC back-end datastore for authorizing requests against policies stored in a MongoDB collection.

Be mindful of the additional overhead of making a network call to MongoDB per request-response cycle.

Install

$ npm install abac-mongodb

Usage

Configure BackEnd and define policies

The MongoDB BackEnd requires a MongoDB connection. The action is used to find the policy document in the policies collection. A policy's rules can be defined as a boolean or a function.

var abac = require('abac'),
    mongoose = require('mongoose'),
    MongoDBBackEnd = require('abac-mongodb').BackEnd;

abac.use(new MongoDBBackEnd(mongoose.connection));
abac.set_policy('mongodb', 'use secret feature', true);

Authorize requests

Use abac.can(backend, action, options), specifying 'mongodb' as the backend. Ensure that the action belongs to a policy defined to be stored in the MongoDB BackEnd.

Routes

var express = require('express'),
    abac = require('abac');

app.post('/users/invite/', abac.can('mongodb', 'invite a friend'), function(req, res, next){
    res.json({msg: 'You sent an invite b/c you could!'});
});

Control flow

var express = require('express'),
    abac = require('abac');

app.get('/', function(req, res, next){
    abac.can('mongodb', 'use secret feature', {
        yes: function() {
            // Do something.
        }.bind(this),
        no: function(err, info) {
            // Do something else.
        }.bind(this)
    })(req, res);
});
